Non-linearity and slow response to change of power setting on our ceramic cook top. On 2/9 it still boils and takes a while to slow down.
one of these days I’ll get round to replacing it with a low current induction cook top.
The usual fault mode on simmerstats used in most cook tops is to end up permanently on full time. I'm not sure if some contacts end up welded together or go open circuit. The part is about $30.
